My seat foam in my '91 is totally trashed. I can see through the seat in a few spots and there is always a little snowfall of crumbled foam at the side of the seat. I like the manual seats and would like to keep them rather than do a seat swap. I am also on a limited budget (I know...a Land Cruiser is a terrible vehicle for a poor boy). I was thinking of buying the new foam from Toyota and then just getting some high quality seat covers to go over everything. I don't know any decent upholstery shops that won't charge an arm and a leg to professionally recover the seats. Is this asking for early failure of the new seat foam? Will the seat covers shift around on top of the foam and wear it out prematurely? Or is this a workable idea? Thanks in advance for any input anyone may have.
